Organized Industrial Zones (OSBs) in Turkey: A Complete Guide for Foreign Investors
Turkey’s industrial landscape is one of its most compelling assets. With more than 300 Organized Industrial Zones (Organize Sanayi Bölgeleri — OSBs) spread across 81 provinces, the country offers foreign manufacturers a ready-made environment that dramatically reduces the time, cost, and complexity of establishing production operations. Whether you’re setting up a greenfield facility or relocating capacity from a higher-cost market, OSBs deserve serious attention.
This guide covers everything foreign investors need to know: what OSBs are, how they differ from free zones, what incentives apply, how to acquire land or a factory unit, and what the practical process looks like.
What Is an Organized Industrial Zone?
An Organized Industrial Zone is a purpose-built industrial area established under Turkish law (Law No. 4562 on Organized Industrial Zones) and managed by a legal entity called the OSB Administrative Board, typically composed of local chambers of industry, commerce, municipalities, and sometimes universities or professional bodies.
OSBs are not operated by the central government — they function as quasi-autonomous institutions with their own governance, infrastructure budgets, and service arms. This matters for investors: your primary relationship in an OSB is with the zone’s management, not a ministry.
Each OSB provides:
- Infrastructure: Roads, electricity, natural gas, water/wastewater, telecommunications, fiber optic
- Parcels and factory units: Ranging from small workshops (500 m²) to multi-hectare greenfield plots
- Shared services: Security, waste management, landscaping, social facilities
- One-stop administrative support: Permitting, utility connections, sometimes even labor recruitment assistance
OSBs vs. Free Zones: Key Differences
Foreign investors often confuse OSBs with free zones (Serbest Bölgeler). They are fundamentally different structures:
| Feature | OSB | Free Zone |
|---|---|---|
| Primary purpose | Domestic & export production | Export-focused trade/manufacturing |
| Customs status | Inside Turkish customs territory | Outside Turkish customs territory |
| VAT on sales to Turkey | Standard VAT applies | VAT applies when goods enter Turkey |
| Land ownership | Can purchase land (title deed) | Typically lease only |
| Location flexibility | 300+ zones across all provinces | ~20 zones, mostly near ports/airports |
| Governance | OSB Administrative Board | Ministry of Trade |
| Best for | Manufacturing for Turkish & export markets | Pure export, trading, logistics |
The simple rule: if you’re producing for both Turkey and export, an OSB is usually the better fit. If your operations are export-only or customs-bonded, a free zone may serve you better.
Tax and Investment Incentives in OSBs
OSBs carry a rich incentive package — both from the zone’s special status and from Turkey’s broader investment incentive system.
1. Corporate Tax Exemption on Land Sales
When an OSB sells a parcel to an investor, the gain is fully exempt from corporate tax for the OSB itself. This keeps land prices competitive.
2. VAT Exemption on Land & Factory Purchases
The purchase of land, buildings, and infrastructure within an OSB is exempt from 20% VAT. On a €5 million factory purchase, that’s a €1 million saving on day one.
3. Property Tax Reduction
Buildings used for production in OSBs benefit from a reduced property tax rate — 50% of the standard rate during the first five years of operation in many zones.
4. Electricity Subsidy
Many OSBs operate their own licensed electricity distribution companies, purchasing bulk power and passing on discounts — typically 10–25% below the national tariff. For energy-intensive manufacturing, this is material.
5. Regional Investment Incentives (TCMB Scheme)
Turkey’s investment incentive system divides the country into six regions (Region 1 through Region 6) based on development level. OSBs receive a one region upgrade under the incentive scheme — meaning an OSB located in a Region 3 province is treated as Region 4 for incentive calculations.
This upgrade unlocks better rates across:
- Tax reduction (CIT reduction for a set period after investment)
- Social security employer contribution support (government covers employer SSI premiums for 2–10 years)
- Interest/profit-share support (subsidized financing via state banks)
- Land allocation (free or discounted public land for qualifying investments)
- VAT exemption on machinery imports
- Customs duty exemption on imported machinery
6. Technology Development Zones (Technoparks) Within OSBs
A growing number of OSBs host an R&D or technology development zone on their grounds. If your operation qualifies, you can layer OSB incentives with technology zone incentives (income tax exemption on R&D personnel, CIT exemption on software/R&D income).
Types of Industrial Zones: Choosing the Right OSB
Sectoral OSBs
Some zones are designated for specific sectors — such as leather & footwear (Uşak), ceramics (Kütahya), food processing (Konya), or defense supply chain (Ankara/Kayseri). Sectoral OSBs offer pre-built supply chains, shared testing labs, and sector-specific infrastructure (e.g., wastewater treatment calibrated for food production).
Mixed-Use OSBs
Most OSBs are open to any industrial activity, subject to the zone’s own environmental classifications and parcel zoning. These offer maximum flexibility for multifunction manufacturing.
OSB with Export Focus (İhracata Yönelik OSB)
Certain OSBs near logistics corridors and ports have been designated as export-oriented, qualifying for additional customs and logistics support.
Small Business OSBs (KOSSBs)
Some zones include a section specifically for small and medium enterprises, with smaller parcel sizes and shared production facilities. Foreign SMEs often find these lower-risk entry points.
How to Acquire Land or a Factory in an OSB
Step 1: Zone Selection
Identify target OSBs based on:
- Province and logistics access (proximity to ports, highways, rail)
- Available parcels (check the OSB’s official portal or the Ministry of Industry’s OSB database at sanayi.gov.tr)
- Sector fit (sectoral zones vs. mixed)
- Utility capacity (gas, power, water availability)
- Labor market (local workforce, vocational schools, wage levels)
Step 2: Application to the OSB Administrative Board
Submit a formal application (parsel tahsis başvurusu) to the OSB management. Required documents typically include:
- Company documents (trade registry certificate, tax number, articles of association)
- Investment project summary (activity description, production capacity, employment projections)
- Financing plan
- Environmental impact declaration (where applicable)
For foreign companies not yet incorporated in Turkey, you will need a Turkish legal entity or branch before a parcel can be formally allocated. The OSB application and company incorporation can run in parallel.
Step 3: Parcel Allocation Committee
The OSB’s allocation committee reviews applications and scores them on criteria including investment amount, employment creation, export potential, and sector fit. High-priority investments (large job creators, technology-intensive activities) get preferential treatment.
Step 4: Preliminary Allocation (Ön Tahsis)
Successful applicants receive a preliminary allocation certificate. This grants a grace period (typically 6–12 months) to finalize financing and begin construction. The investor pays a parcel reservation fee at this stage.
Step 5: Formal Title Deed (Tapu) Transfer
Once payment is made and conditions are met, the title deed transfers to the investor. Foreign-owned companies incorporated in Turkey have the same property rights as domestic companies in OSBs.
Step 6: Construction
Construction must begin within a set period (typically 1–2 years from allocation) and be completed within another defined timeframe (typically 3–4 years). Delays can result in parcel reallocation unless extensions are granted.
Alternatively, many OSBs offer ready-built factory units (hazır işyeri or kiralık fabrika) — either leased directly by the OSB or by private owners who built within the zone. This is the fastest route to operations: lease a ready unit, fit it out, and start production.
Foreign Ownership: What the Law Says
Under Turkey’s Foreign Direct Investment Law (Law No. 4875), foreign investors enjoy the same rights as Turkish nationals in establishing and operating companies. In practice, this means:
- A foreign-owned Turkish LLC (Ltd. Şti.) or Joint Stock Company (A.Ş.) can acquire land and buildings in an OSB without restriction
- Repatriation of profits, dividends, and sale proceeds is freely permitted
- There are no sector restrictions on foreign ownership in most OSB activities (with standard exceptions in defense and certain regulated sectors)
Non-residents or non-Turkish-incorporated entities cannot directly hold OSB parcels — Turkish incorporation is the pre-condition.
Practical Considerations: What Experienced Investors Know
1. Zone readiness varies considerably. Some OSBs have parcels immediately available with all utilities connected. Others have allocated most land and are in expansion phases — meaning a 12–24 month wait for infrastructure. Always verify actual utility status before signing.
2. Environmental permitting is parallel, not sequential. Start your environmental impact assessment (ÇED or ÇED muafiyeti — EIA or EIA exemption) concurrently with parcel application. Waiting until after allocation adds months.
3. Labor supply is zone-specific. An OSB in a major city (Istanbul, Bursa, Izmir) may face labor competition and higher wages. An OSB in Central Anatolia may offer a more stable workforce at lower cost but requires investment in employee transportation or on-site dormitories.
4. OSB management quality matters. The best-run zones (such as OSTIM in Ankara, Bursa OSB, Gebze OSB, or Konya OSB) offer proactive investor services, active permit facilitation, and responsive maintenance. Visit and speak with existing tenants.
5. “Islah OSBs” are legacy zones still being regularized. Some older industrial areas are in the process of becoming formal OSBs (islah OSB). These offer lower land prices but may have incomplete infrastructure or unresolved legal status. Approach with additional due diligence.
Key OSBs to Know by Region
| Region | Notable OSBs | Key Sectors |
|---|---|---|
| Marmara (Istanbul/Bursa) | Gebze OSB, Bursa Nilüfer OSB, TOSB | Automotive, chemicals, electronics |
| Aegean (Izmir/Denizli) | Atatürk (AOSB), Denizli OSB | Textiles, machinery, food |
| Central Anatolia (Ankara/Konya) | OSTIM, İvedik, Konya OSB | Defense, machinery, automotive supply chain |
| Black Sea (Samsun/Trabzon) | Samsun OSB, Trabzon OSB | Food, metals, chemicals |
| Eastern/Southeastern | Gaziantep OSB, Adana Hacı Sabancı | Textiles, plastics, food |
| Inner East (Malatya/Kayseri) | Kayseri OSB, Malatya OSB | Furniture, food, defense |
Eastern zones offer the most generous incentives under Turkey’s regional investment scheme and frequently have available land.
Frequently Asked Questions
Can I lease rather than buy in an OSB? Yes. Both OSBs themselves and private investors who have built within zones regularly offer lease arrangements. Leasing is common for initial entry, giving you operational proof before a long-term land commitment.
Is an OSB necessary for investment incentives? No. Turkey’s investment incentives apply to qualifying investments anywhere in the country. However, being in an OSB delivers the regional “upgrade” and the VAT exemption on land/construction — meaningful advantages for capital-intensive projects.
How long does the full process take from decision to production? For a greenfield parcel: 12–18 months for permitting and construction of a standard industrial building. For a ready-built unit: 1–3 months to sign lease, install equipment, and commence operations.
Are there sector restrictions within OSBs? Each OSB has an approved sector mix in its master plan. Activities with significant environmental or safety risk (certain chemicals, nuclear, heavy metals) may be restricted to designated parcels or excluded altogether. Check the zone’s activity permit list early.
What environmental obligations apply? Depending on the activity, you may need a full Environmental Impact Assessment (ÇED raporu), a notification file (proje tanıtım dosyası), or an exemption letter. OSB management can guide you — most have an environmental engineer on staff.
Next Steps
If you’re evaluating an OSB for your Turkey investment:
- Define your location criteria — logistics, labor, sector proximity
- Request availability data from target OSB management offices
- Apply for investment incentive pre-qualification from the Ministry of Industry (this will determine your incentive region and package before you commit to a parcel)
- Incorporate your Turkish entity — LLC or A.Ş., depending on governance needs
- Submit parcel application to your preferred OSB(s)
